[Vitreous surgery in complicated retinal detachment].

Vitreous surgery in complicated retinal detachment has three main objectives: 1. elimination of traction and mobilization of the retina, 2. inner tamponade of the retina, 3. retinopexy. Pars plana vitrectomy with inner tamponade is indicated: 1. In rhegmatogenous retinal detachment, where vitreous hemorrhage or exsudate make the finding and localization of the retinal break impossible. 2. In rhegmatogenous retinal detachments, where the localization of the break in the posterior eye pole or the size of a giant tear prevent to close the retinal break by means of a cryosurgical procedure with episcleral plombage. 3. In retinal detachment complicated by advanced proliferative vitreoretinopathy: in idiopathic rhegmatogenous detachment, tractional detachment after perforating injury, and in diabetic retinopathy. Vitreous surgery increased the limits of operability in complicated retinal detachments.
